Firstly: Why does the US have a say in that?
Due to integral parts of the aircraft coming from the US. As stated, the engine is from General Electric, giving the US a lever to block the sale. This is quite common, especially for engines, which are very expensive to develop, and as long as everybody get's along, that's no problem.
That also was a problem for the Russians in their civil aviation when western companies left the market. Even new Russian airplanes had so many parts from America/Europe that they had to first be "Russianised".
In our case here it clearly shows the urgent need again to decouple from the US as fast as possible. Especially in defense, all key parts should be from Europe.
Secondly: Separation from the US new imperialistic ambitions starts at the personal level. Use Deepl instead of Google for translations. The quality is better as well.
Absolutely true!
It IS a whole lot and a very strong sign of trust that had to be earned.
The military is one of the most intimate things of a nation and what happened here is a very good sign that hopefully sets an example for others.
